I met a one of these faux investor, charlatan, stone soup types a few years ago. When he talked about making investments, it took a while to figure out he'd invest time and no cash. When he talked about how was was affiliated with some impressive named and organizations, he really meant he'd done a shitty website for a semi well known author and he'd visited the Harvard campus once. At every turn when I asked him for a hard commitment of something I could use, actionable advice or hard cash, he never produced.

I recommend demanding excellence from your investors and expect them to demand excellence from you. Strong relationships improve when tested, others buckle and fade away. That's been my experience anyway.
